1、 Product Introduction

The JC-MLSS-B photoelectric sludge concentration meter is an online analytical instrument designed to measure the concentration of suspended solids in municipal or industrial wastewater treatment processes. Whether evaluating activated sludge and the entire biological treatment process, analyzing wastewater discharged after purification treatment, or detecting sludge concentration at different stages, the Juchuang SS-B photoelectric suspended solids analyzer can provide continuous and accurate measurement results.
The Juchuang JC-MLSS-B photoelectric sludge concentration meter consists of a transmitter and a sensor. Sensors can be conveniently installed in pools, drainage pipes, pressure pipelines, or natural water bodies. The Juchuang MLSS-B photoelectric sludge concentration meter can automatically compensate for interference caused by pollution. The bidirectional digital communication between the transmitter and the sensor can prevent signal attenuation and allow the sensor to be far away from the transmitter. The sensor is equipped with an air cleaning function, which can automatically clean at a pre-set time, greatly reducing the workload of instrument maintenance.

1. Product principle
The attenuation of infrared light transmission and scattering in sludge and suspended solids by Juchuang JC-MLSS-B photoelectric sludge concentration meter is based on the concentration of suspended solids in the liquid. The infrared light emitted by the transmitter on the sensor, after being absorbed, reflected, and scattered by the measured object during transmission, only a small portion of the light can reach the detector. The transmittance of the transmitted light is related to the concentration of the measured wastewater, so the concentration of the wastewater can be calculated by measuring the transmittance of the transmitted light.

Figure 4 Beam Principle Diagram

The sensor of Juchuang JC-MLSS-B photoelectric sludge concentration meter uses four beam technology, as shown in the diagram. Using four beam technology, two emitters and two detectors are used. The light emitted by each emitter is transmitted and directed onto the two detectors, creating a series of optical paths and obtaining a data matrix. By analyzing these data signals, the accurate concentration of suspended solids in the medium can be obtained, and interference can be effectively eliminated to compensate for deviations caused by pollution, enabling the instrument to operate in harsh environments.
Note: The infrared receiver uses an integrated circuit chip that converts high-precision 940nm light intensity into frequency, converting the received light intensity into a digital signal.
